Scum on plastic underneath refrigerator water dispenser?
I have an eight month old stainless steel S x S Kitchenaid refrigerator that has a water and ice dispenser. The plastic part underneath the dispenser where water occasionally drips has what looks like scum (the only way I can describe it - it almost looks like dried milk stains). The only thing that falls there is water but I can't seem to get the thing clean. I have tried cleaning with 409 and microfiber towel but it's still there. Has anyone encountered this? Any suggestions?
